Answer 2

- 7/8 should be added to 3/8 to get - 1/2

Given :

The numbers 3/8 and - 1/2

To find :

The number should be added to 3/8 to get - 1/2

Solution :

Step 1 of 2 :

Form the equation to find the number

Let the required number = x

By the given condition

$\displaystyle \sf{ \frac{3}{8} + x = - \frac{1}{2} }$

Step 2 of 2 :

Find the number

$\displaystyle \sf{ \frac{3}{8} + x = - \frac{1}{2} }$

$\displaystyle \sf{ \implies x = - \frac{1}{2} - \frac{3}{8} }$

$\displaystyle \sf{ \implies x = \frac{ - 4 - 3}{8} }$

$\displaystyle \sf{ \implies x = \frac{ - 7}{8} }$

$\displaystyle \sf{ \implies x = - \frac{ 7}{8} }$

Hence - 7/8 should be added to 3/8 to get - 1/2
